[0015] The present application has the following beneficial effects compared with the prior art:

[0016] 1. The first conveying belt assembly is driven by the power device to move synchronously, and the rotating shaft is driven to rotate, so that the first connecting rod moves up and down, and the second connecting rod moves horizontally through the cooperation of the first connecting rod, the second connecting rod and the third connecting rod, and the stability of the sliding seat is improved through the arrangement of the third connecting rod and the mounting bracket.

[0017] 2. In the actual feeding process, the projections of the conveying wheels on the upper conveying shaft and the lower conveying shaft on the horizontal plane coincide, the outer peripheral walls of the upper and lower conveying wheels abut, and the wire is installed between the upper and lower conveying wheels. The three-way steering box drives the second conveying belt assembly to rotate through the connection of the transmission assembly and the three-way steering box, so that the feeding shaft is driven to rotate, the feeding shaft drives the groove wheel mechanism to work, the groove wheel mechanism drives the lower conveying shaft to rotate to realize the conveying of the wire, and the intermittent movement of the wire conveying is realized through the arrangement of the groove wheel mechanism, so that the wire is cut to the same length in the cutter device, and the quality of the steel ball cold heading processing is improved.

[0018] 4. In the transportation process of the feeding device, the three-way steering box simultaneously drives the second and third conveyor belt assemblies to rotate. The third transmission belt assembly drives the connecting shaft to rotate, and the connecting shaft drives the processing chuck to rotate. The wire passes through the feeding device, is cut by the cutting device, and then passes through the limiting plate into the processing chuck. By setting multiple forming grooves on the processing chuck, the wire will be inserted into the forming groove one by one when the processing chuck rotates, so that the processing device will not process in the same forming groove during processing, thus extending the service life of the device.

[0019] 5. This invention uses a feeding device to feed wire into the channel of the cutting plate. A power device drives the transmission assembly to rotate. Through the cooperation of the first gear and the second gear, the fourth link moves up and down under the rotation of the second gear.

By setting the cutter groove, the neatness of the wire end face can be improved when the cutter cuts the wire, thus improving the quality of subsequent cold heading.

[0020] 6. By setting up a moving component, this invention can improve the smoothness of the movement of the slide block driven by the third link, so that the processing head can better perform cold heading of the wire. At the same time, by setting up the support feet and adjusting screw, the height of the mounting table can be adjusted, and calibration can be performed at the beginning of processing, thereby improving the efficiency and quality of product processing.

Detailed Implementation

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 10As shown: A cold heading machine for bearing steel balls includes a worktable 1, a processing device, a feeding device 4, and a cutting device 5. Wire passes through the feeding device 4 and into the forming groove 31 within the processing chuck 3. The cutting device 5 is positioned between the processing chuck 3 and the feeding device 4. The processing device includes a power unit 2, a first connecting rod 24, a second connecting rod 25, a third connecting rod 26, and a processing head 28. The power unit 2 is located at the bottom of the worktable 1, and its output end is connected to a first conveyor belt assembly 21. A rotating shaft 22 is coaxially mounted on the first conveyor belt assembly 21. A turntable 23 is rotatably mounted on the rotating shaft 22. One end of the first connecting rod 24 is mounted on the turntable 23, and the other end of the first connecting rod 24 extends through to the top of the worktable 1 and is connected to a second connecting rod 25. The second connecting rod 25 is rotatably mounted on a mounting bracket 251, which is fixed to the worktable 1. One end of the third connecting rod 26 is coaxially mounted on the first connecting rod 24 and the second connecting rod 25, and the other end of the third connecting rod 26 is connected to a slide block 27. A processing head 28 is mounted on the slide block 27, and the processing head 28 is aligned with the forming groove 31 on the processing chuck 3.

[0034] In actual processing, the bearing steel ball cold heading equipment transports wire through the feeding device 4, cuts it through the cutting device 5, and then enters the processing chuck 3. By starting the power device 2, preferably a rotary motor, the power device 2 drives the first conveyor belt assembly 21 to move synchronously, which in turn drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the turntable 23 to rotate, thereby realizing the up and down movement of the first connecting rod 24. Through the cooperation of the first connecting rod 24 with the second connecting rod 25 and the third connecting rod 26, the second connecting rod 25 can drive the slide 27 to move horizontally. By setting the third connecting rod 26 and the mounting bracket 251, the stability of the slide 27 movement can be improved. The slide 27 drives the processing head 28 to squeeze in the forming groove 31 of the processing chuck 3, processing the wire into a spherical blank, effectively improving the working efficiency of cold heading and the quality of the finished product.

[0035] Reference Figure 2 , Figure 4 and Figure 5As shown: A transmission assembly 6 is provided on the rotating shaft 22. One end of the transmission assembly 6 is rotatably connected to the rotating shaft 22 on the same axis. The other end of the transmission assembly 6 is connected to a three-way steering box 7. The three-way steering box 7 is fixedly installed below the workbench 1. The other end of the three-way steering box 7 is connected to a second conveyor belt assembly 71. The other end of the second conveyor belt assembly 71 is rotatably connected to the feeding shaft 72. The feeding device 4 includes a feeding bracket 41, a conveying wheel 44, and a grooved wheel mechanism 45. The feeding bracket 41 is fixedly installed on the workbench 1. An upper conveying shaft 42 and a lower conveying shaft 43 are provided inside the feeding bracket 41. The conveying wheel 44 is rotatably installed on the upper conveying shaft 42 and the lower conveying shaft 43. One end of the grooved wheel mechanism 45 is rotatably connected to the lower conveying shaft 43. The other end of the grooved wheel mechanism 45 is rotatably installed on the feeding shaft 72.

[0036] During the actual material feeding process, the projections of the conveyor wheels 44 on the upper conveyor shaft 42 and the lower conveyor shaft 43 on the horizontal plane coincide, and the outer peripheral walls of the two conveyor wheels 44 abut against each other. The wire is installed between the two conveyor wheels 44. The transmission assembly 6 is connected to the three-way steering box 7, which drives the second conveyor belt assembly to rotate, thereby driving the feeding shaft 72 to rotate. The feeding shaft 72 drives the grooved wheel mechanism 45 to work, and the grooved wheel mechanism 45 drives the lower conveyor shaft 43 to rotate to realize the conveying of the wire. By setting the grooved wheel mechanism 45, the wire conveying can be intermittent, so that the wire is cut to a consistent length in the cutting device 5, improving the quality of cold heading of steel balls.

[0037] Reference Figure 4 and Figure 5 As shown: The feeding device 4 is equipped with an adjustment device, which includes guide posts 46, sliders 47 and adjusting bolts 49. The guide posts 46 are arranged on both sides of the feeding bracket 41. The sliders 47 are slidably mounted on the guide posts 46 on both sides. The upper conveying shaft 42 is mounted on the sliders 47 on both sides. A connecting block 48 is arranged between the sliders 47 on both sides. The adjusting bolts 49 pass through the top of the feeding bracket 41 and are fixedly connected to the connecting block 48.

[0038] By setting the adjustment component, when installing the wire, first place the wire on the lower conveyor wheel 44, and adjust the position of the slider 47 on the guide post 46 by adjusting the bolt 49. When the outer peripheral walls of the upper and lower conveyor wheels 44 are tangent, fix the adjusting bolt 49 to make the wire more stable during the conveying process.

[0039] Reference Figure 9As shown: A third conveyor belt assembly 73 is provided on the three-way steering box 7. The other end of the third conveyor belt assembly 73 is rotatably connected to the connecting shaft 74. The machining chuck 3 is rotatably mounted on the connecting shaft 74. A limit plate 75 is provided at the extended end of the connecting shaft 74. The machining chuck 3 is rotatably mounted on the side wall of the limit plate 75. Multiple forming grooves 31 are arranged in a ring on the machining chuck 3.

[0040] During the transport process of the feeding device 4, the three-way steering box 7 simultaneously drives the second conveyor belt assembly 71 and the third conveyor belt assembly 73 to rotate. The third transmission belt assembly drives the connecting shaft 74 to rotate, and the connecting shaft 74 drives the processing chuck 3 to rotate. The wire passes through the feeding device 4, is cut by the cutting device 5, and then passes through the limiting plate 75 into the processing chuck 3. By setting multiple forming grooves 31 on the processing chuck 3, the wire will be inserted into the forming grooves 31 one by one when the processing chuck 3 rotates, so that the processing device will not process in the same forming groove 31 during processing, thus extending the service life of the device.

[0041] Reference Figure 4 , Figure 7 and Figure 8 As shown: The transmission assembly 6 includes a first gear 61, a second gear 62, and a chain 63. The first gear 61 is coaxially rotatably mounted on the rotating shaft 22, and the second gear 62 is rotatably mounted on the three-way steering box 7. The chain 63 is rotatably mounted on the first gear 61 and the second gear 62. The cutting device 5 includes a cutting blade seat 51, a cutting blade plate 53, and a cutting tool. A fourth connecting rod 621 is provided on the second gear 62. The other end of the fourth connecting rod 621 passes through the worktable 1 and is connected to the cutting tool. A cutting groove 52 is provided on the cutting blade seat 51, and the cutting tool is slidably mounted in the cutting groove 52. The cutting blade plate 53 is provided on the side wall of the cutting blade seat 51, and the cutting tool extends into the cutting blade plate 53. A channel 54 is provided in the cutting blade plate 53, and a cutting end 55 is provided in the middle of the channel 54. The output end of the cutting tool is adapted to the cutting end 55.

[0042] The wire enters through the channel 54 of the cutting plate 53 via the feeding device 4. The transmission component 6 is rotated by the power device 2. Through the cooperation of the first gear 61 and the second gear 62, the fourth connecting rod 621 moves up and down under the rotation of the second gear 62. This causes the cutter connected to the top of the fourth connecting rod 621 to move up and down in the cutter groove 52 of the cutter holder 51, thus cutting the wire in the cutting plate 53. By setting the cutter groove 52, the neatness of the wire end face can be improved when the cutter cuts the wire, thereby improving the quality of subsequent cold heading processing.

[0043] Reference Figure 3As shown: It also includes a movable component, which includes a mounting platform 8, a slide rail 81, and an adjusting screw 83; the slide rail 81 is mounted on the mounting platform 8, and a sliding block is provided at the bottom of the slide base 27. The sliding block slides in cooperation with the slide rail 81. A support leg 82 is provided below the mounting platform 8 and is provided through the worktable 1. The adjusting screw 83 is located at the middle of the bottom of the mounting platform 8, and the bottom of the adjusting screw 83 passes through the worktable 1 and is connected to a rotating handle 84.

[0044] By setting up the moving component, the smoothness of the movement of the slide block 27 driven by the third link 26 can be improved, so that the processing head 28 can better perform cold heading of the wire. At the same time, by setting up the support leg 82 and the adjusting screw 83, the height of the mounting table 8 can be adjusted, and calibration can be performed at the beginning of processing to improve the efficiency and quality of product processing.

[0045] Reference Figure 9 and Figure 10 As shown: The second conveyor belt assembly 71 has a positioning plate 11 on its side wall. The positioning plate 11 is fixedly installed on the worktable 1. The connecting shaft 74 passes through the positioning plate 11. The positioning plate 11 is provided with a positioning seat 12. The output end of the processing head 28 is slidably disposed in the positioning seat 12.

[0046] The machining head 28 can be positioned by setting the positioning plate 11 and the positioning seat 12, so that the output end of the machining head 28 is aligned with the forming groove 31 of the machining chuck 3. This improves the quality of the product during processing and reduces the amount of machining blanks.

[0047] Reference Figure 10 As shown: It also includes a collection device, which includes a collection trough 9 and a receiving inclined plate 91. The collection trough 9 is disposed on the side wall of the positioning plate 11. The collection trough 9 is aligned with the direction in which the wire enters the forming trough 31. The receiving inclined plate 91 is disposed at the discharge port of the collection trough 9. The discharge port is disposed at the positioning plate 11.

[0048] By setting up a collection device, the steel ball blanks after cold heading can be collected quickly. After the wire is inserted into the forming groove 31 by the feeding device 4, the formed steel ball blanks are pushed into the collection groove 9 and collected from the receiving inclined plate 91 through the discharge port.

[0049] Reference Figure 8 As shown: A gap is provided below the cut-out 55.

[0050] By setting a gap, when the tool cuts the wire at the cutting point 55, the waste generated from cutting the wire enters the gap, preventing the waste from accumulating at the cutting point 55 and affecting the accuracy of subsequent cutting of the wire end face by the tool, thus affecting the subsequent cold heading process.

[0051] Reference Figure 2 As shown: A stabilizing support 13 is provided on the rotating shaft 22. The stabilizing support 13 is fixedly installed on the bottom of the workbench 1, and the rotating shaft 22 is rotatably mounted on the stabilizing support 13.

[0052] By setting a stable support 13, the stability of the rotating shaft 22 in the working state is improved, and the stability of the first connecting rod 24 when moving up and down is also improved.

[0053] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
